GEORGE HEITLER, on NEW YORK, N. Y.

AN TISLIPPING DEVICE.

Application filed February 1, 1919.

To all whom it may concern:

Be it known that I, GEORGE I'IEITLER, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Antislipping Devices, of which the following is a specification.

This invention relates to a safety attachment, designed for use in connection with boots, shoes or other foot-gear, to prevent slipping or sliding and the injuries which frequently result therefrom.

The principal objects of the invention are: (1) to provide antislipping devices for boots, shoes and the like, designed to give the user a firm hold or footing when walking on wet, icy, or otherwise slippery streets, when ascending or descending inclined places, or when climbing precipitous regions (2) to provide devices of this character which may be readily attached to and as readily removed from, the boots or shoes by the user himself; and (3) to provide devices of this character which are simple in construction, comparatively inexpensive to manufacture, and efiicient in service.

Vith the foregoing objects and others in view, the invention resides in the details of construction hereinafter described, defined in the claims, and illustrated in the accompanying drawings, forming a material part of this specification, and in which Figure 1 is a view in side elevation of a shoe, showin my anti-slipping devices applied thereto.

Fig. 2 is a plan view of the underneath side of the shoe, showing the devices applied.

Fig. 3 is a sectional view, taken in the direction of line 33 of Fig 2.

Fig. 45 is a fragmental view, taken in the direction of line t4c of Fig. 2.

Fig. 5 is a sectional view, taken in the direction of line 55 of Fig. 2.

Fig. 6 is a fragmental top plan view, the same illustrating in particular how the hook-shaped parts or ends are engaged over the sole of the shoe.

In the accompanying drawings, the numeral 7 is employed to denote a shoe, made with the usual sole element 8 and with the usual heel element 9, to which, respectively,

Specification of Letters Patent.

Serial No. 274,466.

I may attach the anti-slipping devices as 10 and 11.

Each device is formed from a single bar or length of metal, preferably of steel of a relatively resilient character, although it may be made of other suitable materials. Each bar or length, between its extremities, is bent upon itself in the same plane, first forwardly and then rearwardly, providing curved obliquely projecting forward portions 12 and curved obliquely-projecting rear portions 13. The intermediate portion or region, thus sinuously bent, is provided, on its underneath side with a concave channel It so as to produce the confronting edges 15.

As best seen in Figs. 3 and 6, the extremities of the device 10 are bent first upwardly as at 16 and then inwardly as at 17, forming hook-like parts which engage over the edges 18 of the shoe sole, whereby this device is secured in place in an obvious manner.

From Figs. 4 and 5, it will be seen that the extremities of the device 11 are bent upwardly to provide lugs as 19, which are corrugated as at 20 on their inner faces so as to firmly grip the heel 9.

Being made of resilient material and with the curved portions 12 and 13, the devices 10 and 11 can be stretched longitudinally for a degree sufficient to permit of the ready application and removal. By reason of their intermediate sinuous regions, which are provided on their undersides with the confronting gripping edges 15, these devices give the wearer a firm hold or footing, when walking on slippery streets or pavements, and when crossing inclined or precipitous regions.

From the foregoing taken in connection with the accompanying drawings, it will be readily understood that either of the antislipping devices may be used effectively without the other; and it will also be understood that changes and alterations in the precise details of the invention, as herein set forth and "illustrated, may be made, to which changes and alterations the inventor is entitled, provided the same are effected within the scope of what is claimed.

Having thus described my invention, what I claim is 1. An antislipping device for boots, shoes and the like, consisting of a single length of resilient material provided with a sinuously bent intermediate region, conc aved in cross-section to produce gripping edges, upturned extremities and means thereon to engage the sole or heel.

2. An anti-gripping device for boots, shoes and the like, consisting of a single length of resilient material having an intermediate region sinuously bent and formed lengthwise with confronting gripping edges, and upturned extremities for embracing the sole or heel elements.

In testimony whereof I have signed my name to this specification.

GEORGE HEITLER.
